Sintrol S300 Dust Monitors Automatic Range setup No manual adjustment required Automatic drift compensation Colour of particles will not affect the reading No optical windows to be kept clean Buildup of dust on the probe will not affect monitoring No alignment required Vibration has no effect on the reading S301 Designed as a filter bag leak detection monitor. Equipped with two independent alarm relays which can be used for early warning and failure, or connected to alarm-devices, it is used to detect filter deterioration and blockage or breakage. The alarms can be used for process control (as an ON-OFF system) in flow no flow situations in bulk solids handling and pneumatic transport applications. Very fast response time, a typical charateristic of these monitors, enables early detection and prevention of expensive product loss to the environment. S303 Also has a 4 20 ma analog signal output used for trend monitoring. It is installed downstream of a filter, cyclone, dryer, or similar devices to monitor the filter performance as well particulate emissions. It has two alarm relays which will energise when the amount of particulate in the gas stream exceeds a preset level. It can also be used for process control in certain applications. S301 and S303 are designed for use in any process fitted with bag, ceramic, or cartridge filters or cyclones where indicative (qualitative) monitoring is required.

This Directive classifies areas into Zone 0, 1, 2 for gas and 20, 21 or 22 for dust and ensures that only ATEX certified systems are installed in the areas. Products are required to be categorised by the level of protection that they offer against the risk of them becoming a potential source of ignition in an explosive atmosphere. The equipment conformity categories are 1, 2 & 3. Split Architecture (Remote ) models S300 Series include the following remote models: S311, S313, S314 and S315. The remote models are used when the sensor has to be installed on a pipe, duct or stack but the control unit up to 200 meters away in control room. In these models, the sensor is connected to an enclosure housing the preamplifier (PA) and the amplified signal is transmitted with a 4-wire shielded cable using one of the recommended cables.

Comparison of S304 / S305 and an Optical Dust Monitor Time Surge caused by hammering Detected by S303/S304 dust monitor Optical method measurement Data is presented from parallel testing of a S304 / S305 dust monitor and an optical monitor both installed downstream of an electrostatic precipitator (ESP) in a cement plant. Peaks in the signal outputs from the instruments correspond to hammering of the ESP which is carried out periodically to remove the particulate matter from the precipitating electrode. Fast response time of the S304 / S305 is one of the excellent characteristics of these dust monitors. Principle of Operation In the S300 series monitors DC component of the signal is mathematically filtered out and stored for use if required. Only the AC component of the signal is used for monitoring solid particles. The signal is obtained by the particles impacting the sensor rod or passing nearby. Both modes of charge transfer, impaction and induction contribute towards the signal acquisition. The monitor is not affected by particle buildup on the probe. Automatic Setup Procedure With no optical windows to be kept clean and no problem of the alignment of the light axis, S304 and S305 proved to be an excellent choice for monitoring of dust in the stack of the cement plant. Tests and Test Results Extensive tests carried out with different types of particulate matter in Finland and Germany showed S304 / S305 s excellent linearity with various dust types. The particulates used included test dusts with known particle size distributions as well as ash from coal fired power plants. The Figure, shows the linearity of these monitors for a typical dust. (Particle size: 1 10 microns). S300 Series dust Monitors utilise a unique method of detecting dust particles. The received signal is analysed in the 16-bit microcontroller of the monitor over a period of time and the average value determined. The monitor then selects the right range itself. No manual range setup is required.
Typical Applications Cement manufacture Chemical processing Metals industry Foundries Pharmaceutical industry Mineral drying Fertilisers Wood processing Food and tobacco Rubber compounding Animal feed processing Power plants Waste incinerators Pulp and paper Typical Trend-Monitoring Application (Dryers) The schematic diagram below shows an application where S300 series dust monitors are installed after a filtration system to monitor the solid flow continuously downstream of the filters and also to detect leakage or filter breakage. age. Back pulsing is carried out one compartment at a time to avoid condensation and clogging. The first compartment is being back pulsed in this picture. Fan is alweays operated for back pulsing. Trend monitoring data shows that there is a correlation between dust concentration and signal output of the S303 Dust Monitor. This dust monitor was operated for several months without maintenance. Foundry S300 dust monitors are installed after the baghouses (or electrostatic precipitators in some cases) to monitor these particulate arrestment systems. The continuous ma signal outputs at points 1 and 2 give information on filter wear and tear. The S304 / S305 installed at point 3 is used to measure the total emission of foundry dust, i.e. for stack-monitoring.
Dust Measurement of Coal-fired Power Plant Flue Gas with S300 Series Dust Monitors Flue gases from pulverized coal fired power plants contain particulate matter that have to be removed to comply with stringent environmental regulations. Electrostatic precipitators (ESP) are used for this purpose. p Continuous monitoring of particulate matter in the flue gas is needed to maintain high efficiency of the ESP and to detect its abnormal operation. S304 and S305 dust monitors are used for this purpose because of their excellent characteristics and easy maintenance. S300 series dust monitor Fluegas desulfurization system Dust Measurement of Cement Kiln s Exhaust gas with S300 Series Dust Monitors The exhaust gases from a cement manufacturing plant contain particulate matter that have to be removed to comply with stringent environmental regulations. Electrostatic precipitators (ESP) are used to reduce the particulate matter to an acceptable level. S304 and S305 dust monitors are used to monitor the ESP as well as the particulate matter downstream of the ESP. Environmental Standards A reliable and accurate dust monitoring system is needed to satisfy the continuous monitoring requirements of the environmental regulatory authorities and to ensure compliance with increasingly stringent standards imposed for particulate emissions to the atmosphere. Sintrol s S304 and S305 dust monitors are proving an ideal solution for stack-monitoring requirements of a variety of applications including coal-fired power plants and incinerators. TÜV certification includes: 13 BImSchV, 17 BImSchV, 27 BImSchV, 30 BImSchV and TA Luft 2002.
